The Lowdown
Alright folks, Rusty here. Let's be straight with you. Looking at the whole 16-day window for Kennebunk Beach, it's a tough stretch. We're looking at a long, dry spell with barely a ripple for the first twelve days, then a very brief pulse of something rideable before it fades again. Don't get your hopes up too high.
For the first week and a half, from Wednesday, August 5th right through to Sunday, August 16th, it's a flat spell. Morning after morning brings glassy, clean conditions, but with swell heights barely cracking 2 feet and the combined energy struggling to get past a paltry 44 (the lowest of the low), there's just nothing to surf. The water temp is sitting at 65°, which is bang on average for this time of year. The afternoons are mostly a write-off with choppy cross-onshore breezes. It's a real lull, and it stretches on for days.
Now, that changes on Monday, August 17th. The morning brings a sudden spike in energy. We're looking at a 6ft swell from the SE, pushing combined energy up to a solid 444 (moderate). That's the biggest push of the whole forecast. The wind is light and clean out of the ENE, which is a nice offshore angle for this sheltered spot. It’s a small window of properly surfable waves. The period is a short 7 seconds though, so it'll be a bit lumpy and crumbly, not the cleanest lines. That afternoon sees the swell drop to 4ft with energy down to 159, still rideable with offshore NE wind, but not as good.
After that little burst, it's back to small stuff. Tuesday, August 18th morning has a weak 2ft swell with 140 energy and glassy conditions, but it’s not really a standout. The rest of the week fades back into the flatness we saw at the start.
So, where's the best? The clear standout is Monday morning, August 17th. That’s your only real shot at a wave. The water is a bit cooler after that pulse, but it’s the only window with size and clean wind. If you're an experienced surfer, the 6ft swell is manageable, but it's got enough push to be a handful for beginners. The winds are offshore and light, keeping the surface clean. The short period means it'll be a bit of a close-out at the beach, but it's what we've got.
Crowds are a possibility here, but with such a long flat spell, I'd expect most folks to be caught off guard. It's inconsistent, but when it shows, it's a rare treat.
This is Rusty, signing off.

A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
